I suspect a lot of the benefit of using a torque wrench on 7s is consistency rather than absolute values. A simple test like Charles mentions will tell you if it's more or less accurate.
On assembling my engine I suspect the only place I will use mine is with the Phoenix big end bolts (since there is a recommended value for them I think?) and the head studs, just to get them all the same.
Calibration and accuracy of measuring equipment is always an interesting problem. I have a bunch of different temperature measuring devices, electronic and physical, they all read differently so you're never sure which one is 'right'.
There's even is a name for it, Segal's law (not Steven).
